I'm not really social either, I'm tired, pregnant and she's 2 and all over the place and I don't have the mental capacity to deal with her running down the street away from me every time we set foot outside. I try and go out when her dad gets home for a bit of fresh air but he gets home later than id like but he gets to chase her all around. I do have that fear too of someone wanting to harm my baby but I've always been a detailed person, constantly scanning my surroundings and if I feel uncomfortable, we're not staying.
Have you tried talking to a therapist? That sounds like some anxiety.
Quite often I feel like that. I kind of don't want to go outside just because I'm tired all the time.
